How to build it
**( 1 ) **Assemble the outhouse over a hole that you've dug measuring 3x3x3 feet. Lay down a 48x48-inch foundation frame of 2x4s (with space for the hole). Construct a 48x48-inch double-layered floor joist box, using 2x8-inch treated lumber (joists running front to back) and set this atop the foundation. Cover the joist box with a 5/8-inch exterior plywood floor, centering a 12x24-inch opening on the back side. Then make a bench seat from 2x4s, 24 inches wide and 18 inches high, covered with 1-inch-thick boards. The toilet seat opening is 10x12 inches.
